TYPEWRITING MACT-ITN E.

Application led Gotober 10, 1925. Serial No. 61,S52.

This invention relates to typewriting machines, and has particular reference to attachments for holding and line-spacing relatively small work-sheets, such as visible index filing cards or the like, in position for typing adjacent their bottom edges.

An important feature of the invention is the provision of a work-holder for small work-sheets, wherein the leading edge of a sheet may be located in a predetermined position, and wherein it may subsequently be linespaced relatively to said predetermined position.

In carrying out the invention, a work-table is provided preferably formed of a pair of aligned plates, said plates being adjustably mounted and preferably tangential to the typewriter platen at the` printing line thereof. Each plate is provided at its outer edge with al side gage overlapping the plate, these two gages combining to form a chute for the re; eption of a downwardly inserted work-sheet; and portions of the side gages overlap the plates and are resilie-ntly formed in such a manner as to securely clamp the work-sheet in position. Extending upwardly from each plate, and preferably formed integrally therewith, are gage supports carrying slidably mounted upper edge gages. These upper edge gages include a forwardly-extending portion serving as a stop to locate the work-sheet in a definite position, and below the stops is a plurality of line-space indicators by which the work-sheet may be line-spaced, By having the upper edge gages adj ustable towards and away from the platen, work-sheets of different sizes may be easily handled.

Other features and advantages will hereinafter appear.

In the accompanying drawings,

Figure 1 is a front elevation of a portion of a typewriting machine with my invention applied thereto. f

Figure 2 is a vertical transverse sectional view.

Figure 3 is a detail perspective view of one of the upper edge gages.

rThe invention may be applied to any typewriting machine including a platen 10 having a shaft 11 rotatably mounted in end plates 12 of an ordinary shifting frame. The end plates 12 support a longitudinal bar 13 attached by means of thumb-screws 14, and upon which a pair of aligned plates 15 and 16 are adjustably mounted. Each of the plates 15 and 16 carries at its outer side edge a gage member 17, which 1s suitably formed to provide a chute for the reception of a work-sheet 18, and has a workclamping portion 19 overlying the corresponding plate and resiliently formed to embrace a work-sheet. Depending lingers 20 extend slightly below the printing line of the platen 10 and are correspondingly curved, as clearly shown in Figure 2, so as to press the work-sheet against the platen and have itconform to the shape thereof. The longitudinal bar 13 is provided with oblong slots 21 for the reception of fastening screws 22, which have their heads disposed in recesses 23 in the plates 15 and 16. By this arrangement,` relative adjustability of the plates permits the use of the work-holder for work-sheets of different sizes.

Extending upwardly from each plate 15 and 16, and preferably integral therewith, are gage supports 24 upon which are slidably mounted leading-edge gages designated generally by the reference character 25. The leading-edge gages are preferably formed of sheet-material, and have a forwardly-extending portion 26, which acts as a stop for positioning the leading edge of the work-sheet, and downwardly-extending portion or tab 27 which is in substantially the same plane as the work-sheet and provided with a plurality of scored lines 28, whic-hare equi-distantly spaced to correspond to the regular line-spacing of a standard typewriting machine. Setscrews 29, carried by the gages 25, serve to hold the gages in adjusted positions on the supporting par 24.

From the foregoing, it will be evident that as the work-sheet 18 is placed in position upon the work-table formed by the plates 15 and 16, its upper edge may be gaged by the forwardlyextending portions 26, so as to locate the worksheet in a predetermined position. As shown in Figure 1, such location will permit typing adjacent the lower edge, as indicated at 30, after which, if it is desired to perform additional typing, the work-sheet may be moved downwardly to a position wherein its upper edge is in line with one of the scored lines 28, whereupon an additional line of typing, as at 31, may be typed.

The invention is particularly adaptable for use in connection with visible index tiling cards, wherein certain data is typed at the lower edge thereof, and which, in some cases, require additional miscellaneous information to be typed as closely as possible to the rst imprinted information. lVhile it is herein disclosed as being used for typing adjacent the lower edge of the work-sheet, it will, of course', be understood that the invention is equally adaptable for typing upon any otherI part of the work-sheet, the main point being that typing may be done on a predetermined portion of the work-sheet, and additional matter line-spaced relatively to the predetermined position.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.

Having thus described my invention, I claim: y

1. In a typewriting machine, the combination with a platen, of a work-table for supporting a work-piece in printing position before the platen, a gage-support extending upwardly from the work-table, adjustable gaging means mounted on the gage-support, said adjustable gaging means including a forwardly-extending abutment for the upper edge of Vthe work-piece, and a depending member having line-space-gaging means with which the leading edge of the work-piece may be selectively aligned.

2. In a typewriting machine, the combination with a platen, of means for supporting a work-piece in position for typing adjacent the platen, adjustable gages for locating the work-piece in predetermined position, and auxiliary line-space gages carried by the adjustable gages whereby the work-piece may be line-spaced relatively to the predcteri'nined position.

3. An attachment for a typewriting ma` chine including a work-table, means to hold va Work-piece on the work-table in position for typing adjacent its bottom edge,'stops to engage one horizontal edge of the workpiece to locate it in predetermined position,

said stops being adjustable toward and away from the printing line, and line-space gages depending from the stops and adjustable therewith.v

4. An attachment for a typewriting machine including a work-table, means to hold a work-piece on the work-table in position for typing adjacent its bottom edge, gagesupports extending upwardly from the worktable, stops slidable on the gage-supports, each stop including a forwardly-extending portion to engage the leading edge of the work-piece to locate it in predetermined position for typing, and a downwardly-extending portion having spaced scores at line-space distances apart, whereby to line-space the work-piece relatively to the first position.

5. In a typewriting machine, the combination with a revoluble platen and a platenframe, of means mounted on said platenframe and disposed at the delivery side of the platen for the purpose of directly presenting stifl work-pieces of different heights to the front of the platen and holding leach of the i same to the platen, includinga work-table mounted wholly above the printing point and lying close tothe platen for supporting in printing position before the platen a workpiece pendent therefrom, said table having means in front of the work-piece to confine the same to the platen, a gage-support extending upwardly from the work-table, and a gage mounted on said gage-su port in such manner as to be bodily mova le along the same for up and down adjustment thereof, said gage including a forwardly-extending abutment for the leading edge of said workpiece, and a depending scale provided with a series of line-space graduations with which said leading edge may be selectively aligned, said scale adjustable with said gage.
